“Every savage can dance” is a quote from Pride and Prejudice (said by Mr. Darcy) by Jane Austen.
Excerpt from Chapter 6 of Pride and Prejudice:
“What a charming amusement for young people this is, Mr. Darcy! — There is nothing like dancing after all. — I consider it as one of the first refinements of polished societies.”
“Certainly, Sir; — and it has the advantage also of being in vogue amongst the less polished societies of the world.
— Every savage can dance.”
